Category: Fertilizer granulator machine

So far, more and more people are joining in the production of organic fertilizer. The most common and convenient method people choose is to make organic materials into pellets.

So if you want to make organic fertilizer particles, the choice of granulator is particularly important. At present, the most popular choice is drum granulator and disc granulator. These two granulators have been used in large organic fertilizer wet granulator plants. So if you want to build a small yield organic fertilizer pelletizing plant, how to make fertilizer balls economically is a key problem. In addition to large organic fertilizer granulator, we also have a granulator specialized for the production of a small amount of dry fertilizer particles: dry extrusion granulation equipment. Using dry extrusion granulation, the produced particles do not need drying and cooling. You can pack them directly, which saves you a big part of the cost of machines like dryers.

 The fertilizer particles are cylindrical in diameter about 3-8mm. If you want fertilizer balls, we have polishers. Fertilizer polishing equipment is used with fertilizer granulator auxiliary machine. The appearance of fertilizer particles is more uniform and rounded. For small organic fertilizer production lines, connecting the flat granulator to the polishing machine can get round fertilizer balls more economically than using other granulators. If you want to make large organic fertilizer balls in this way, you only need to buy some flat mold granulator, we can design a reasonable layout and production line for you.

Advantages of using disc granulator to process chicken manure organic fertilizer

1. The chicken manure organic fertilizer does not contain any chemical components. Due to the poor digestion ability of the chicken, it can only consume 25 nutrients, while the other 75 nutrients in the feed are discharged with the feces, so that the dry product contains nitrogen, phosphorus, potassium, organic matter, amino acid, protein and other components.

2. The main substance in chicken manure organic fertilizer is organic matter, which increases the content of organic matter in soil. Organic matter can improve soil physical, chemical and biological properties, ripen the soil, and improve soil fertility. The proverbs that the land depends on dung and the seedlings grow on dung in rural areas of China reflect the role of chicken manure organic fertilizer in improving soil to a certain extent.

3. Chicken manure organic fertilizer not only increases many organic colloids, but also decomposes and converts many organic substances into organic colloids through the action of microorganisms, which greatly increases the adsorption surface of the soil, and produces a lot of sticky substances, making the soil particles cemented into stable aggregate structure, improving the soil’s water, fertilizer and air permeability properties, as well as the ability to adjust the soil temperature.

4. Chicken manure organic fertilizer can also make a large number of microorganisms in the soil multiply, especially many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, nitrifying bacteria, etc. Chicken manure organic fertilizer contains various active enzymes secreted by the digestive tract of animals and various enzymes produced by microorganisms. These substances can greatly improve the enzyme activity of the soil after being applied to the soil.

Applying more chicken manure organic fertilizer can improve soil activity and biological reproduction and transformation ability, thus improving soil absorption, buffering and stress resistance.

The disc granulator is applicable to the granulation of organic fertilizer, compound fertilizer, compound fertilizer and organic-inorganic compound fertilizer: the disc granulator is face to face, easy to control and flexible to adjust. A water spray device is installed above the disc to make it spray out in the form of fog, and the materials are continuously flowing into the rotating disc by the belt conveyor or other conveying equipment, and are carried to the top with the rotation of the disc. Then it falls along the bottom of the disc to the bottom. At the same time, due to the addition of misty water, the material gradually forms particles in the process of rotating and falling with the disc. As time goes on, the particles gradually increase. The disc granulator is designed with an angle adjustment mechanism. The user can determine the inclination angle of the disc according to the size of the required particles. Generally, the inclination angle of the disc can be adjusted between 35 ° and 50 °, and the particles meeting the specifications are floating above the inclined disc, As the disc rotates, the particles are thrown out along the tangential direction of the disc, and then flow into the feed inlet of the belt conveyor and pulled into the next link.

The small organic fertilizer processing equipment is suitable for the treatment of small farm manure, which not only solves the problem of manure, but also increases the income of the farm. The whole set of organic fertilizer production line can be operated by only 2-3 people, and the complete set of powdered organic fertilizer equipment can meet the production demand of about 40000 to 60000 yuan

Disc fertilizer granulator machine of pelletizer: The advantages of swine manure organic fertilizer in pellet production of pig manure organic fertilizer need our attention.

1. Operational problems, the pig manure organic fertilizer disc granulator is relatively straightforward to operate, there are not so many complicated procedures, and you can always keep track of the operation of the granulator equipment.

2. The pig manure organic fertilizer disc granulator is suitable for large, medium and small enterprises. Granulators are widely used. As long as the fertilizer is related to granules, it can be granulated using a granulator without any conditions.

3. Pelletizing of pig manure organic fertilizer, that is, the control range of the particle size is very wide, the spheroidization rate is very high, and the spheroidization can reach about 90%.

The use process of the disc pelletizer; the treated pig manure is directly transported to the raw material mixer, and the pig manure is transferred to the homogenizer, and evenly added to the rotating disc of the disc pelletizer. The rotating disc and the edge of the disc produce friction and centrifugal action on the material, causing the material to move in a circumferential direction, and the particles are rubbed and squeezed with each other, and gradually reunite into a ball; due to the difference in particle quality, the resulting gravity and The centrifugal effect is also different. When the gravity and centrifugal effect increase enough to overcome the friction between the particles, they will be thrown out of the disk, and the smaller particles remain in the disk to continue to accumulate fine powder particles.

Performance characteristics of organic fertilizer granulator: for organic fertilizer raw materials, livestock manure and urine, compost fertilizer, green fertilizer, sea fertilizer, cake fertilizer, peat, soil and miscellaneous fertilizer, microorganism and other urban domestic garbage The new organic fertilizer granulator has the specificity of organic fermentation fertilizer granulation, and the particles are pellets. The machine is suitable for a variety of different formulations. The compressive strength of organic fertilizer is higher than that of disc and drum, and the large ball rate is lower than 15%. The particle size uniformity can be adjusted through stepless speed regulation function according to user requirements. This machine is suitable for direct granulation of organic fertilizer after fermentation to reduce manufacturing costs.

The process flow of the powdery organic fertilizer production line is as follows:

1. First, mix chicken dung with proper amount of straw powder. The amount depends on the water content of chicken dung. Generally, 45% water content is required for fermentation. That is to say, knead it into a ball, see water in the fingers, but do not drip, and release it to dissolve

2. Then add the prepared mixture into the mixer for mixing. The mixing must be uniform, transparent and free of raw blocks

3. The raw materials are fed into the fermentation tank to add the fermentation bacteria. The fermentation tank is built into a 2.5 m wide and 0.8 m-1 m high strip, which is flipped once every 2 days (the length, width and height of the fermentation tank can be determined according to the actual site). The fermentation of bacteria used here is mainly for rapid temperature rise, fermentation, deodorization, and elimination of harmful bacteria. The fermentation tank is stacked for 2 days of temperature rise, 4 days of odorlessness, 7 days of looseness, and 9 days of fragrance Fertilization in 10 days. Specifically, the temperature on the second day of composting can reach 60 ℃ – 80 ℃ (different temperature changes in different seasons) to eliminate diseases and pests such as Escherichia coli and insect eggs; The stink of chicken manure was removed on the fourth day; On the 7th day, the compost became loose and dry and covered with white hyphae; On the 9th day, it sent out a kind of liquor flavor; On the tenth day, the bacterial fertilizer will mature

4. Crush with semi-wet material crusher

5. Then the impurities are screened out by the screening machine to make powdery organic fertilizer

6. The organic fertilizer production line can be packaged and stored by automatic packaging machine

The working principle of the drum granulator is that the belt and pulley are driven by the main motor and transmitted to the driving shaft through the reducer. The split gear installed on the driving shaft is engaged with the large gear ring fixed on the body and works in opposite direction. The material is added from the feed end and passed through the cylinder. It is made into particles by the special structure inside the cylinder, and then flows out through the outlet. Because of the continuous entry of materials and the continuous rotation of the granulator, mass production can be realized.

Overview of drum granulator structure The whole machine can be divided into five parts:

Bracket part: the whole rotating part of the machine body is supported by the bracket, which bears a large force. Therefore, the bracket part of the machine is made of medium carbon steel plate and channel steel dryly, and has passed strict quality control and special process requirements, which has reached the purpose of the machine. In addition, it is more important to fix the supporting roller on the rack. Considering that it will cause great friction with the body rolling belt, our factory specially selects anti-corrosion and wear-resistant materials, which greatly improves the service life of the machine. The supporting roller frame also adopts the casting integration technology. In addition, there are lifting hooks at the four corners of the supporting roller frame, which is convenient for loading, unloading and transportation

Drive part: the drive part of the whole granulator is the most important part. The whole body works in this way. The drive frame is made of high-quality channel steel dryly connected, and has passed the strict quality requirements. The main motor and reducer installed on the drive frame are ISO performance reliable products, and the quality is reliable. The motor drives the pulley, triangular belt, and reducer to the main shaft, so that the body works, The transmission reducer is driven by nylon shaft pin coupling in the main shaft working part.

Big gear: fixed on the machine body, it fits with the transmission pinion and drives the machine body to work in the opposite direction. It uses high-tech wear-resistant materials, so that the service life of the machine is longer.

Rolling belt: fixed to both sides of the body to support the whole body.

Body part: The body part of the whole granulator is particularly important. It is made of high-quality and medium-carbon steel plate dryly connected, with special rubber lining plate or acid-resistant stainless steel lining plate built in, to achieve automatic scar removal and tumor removal, eliminating the traditional scraper device, and achieving the purpose of this machine through strict quality control and special process requirements.

The drum granulator is especially suitable for granulation of light fine powder materials, especially for granulation of organic compound fertilizers. The finer the basic particles of the fine powder material, the higher the sphericity of the particles, and the better the balling quality. It is generally required that the particle size of materials before granulation should be less than 50 mesh. Typical application materials: chicken manure, pig manure, cow manure, carbon black, clay, kaolin, carbon, phosphorus and potassium and other organic compound fertilizers are suitable. The granulator developed and produced by our company is based on the manufacturing principle and technology of the stirrer granulator and the drum granulator. It is carefully developed and repeatedly tested. The granulator can produce bacteria at normal temperature, with reasonable structure design, and can produce spherical granular products. The granulator has the characteristics of low water content, easy drying, high molding rate, good particle strength, and beautiful appearance. It is the ideal bio-organic fertilizer and organic-inorganic fertilizer today, Granulation equipment for organic and inorganic compound fertilizers.

Organic fertilizer granulator machine can effectively solve the environmental pollution caused by the excrement discharge of the aquaculture industry, thereby reducing the eutrophication caused by surface and groundwater pollution caused by organic waste, which is conducive to improving the safety and quality of agricultural products, and for the comprehensive cultivation of edible green vegetable melons If a good foundation is laid, the ecological and environmental benefits are extremely significant.

The characteristics of the organic fertilizer granulator are:
1. The granules produced are spherical.
2. The organic matter content can be as high as 100%, to achieve pure organic matter granulation.
3. The organic particles can be inlaid with each other under a certain force, and there is no need to add a binder during granulation.
4. The granules are solid and can be sieved after granulation to reduce drying energy consumption.
5. The organic matter after fermentation does not need to be dried, and the moisture content of the raw material can be 20-40%.

The scope of application of organic fertilizer granulator is also very wide. The finer the basic particles of organic materials, the higher the sphericity of the particles and the better the quality of the balls. It is generally required that the particle size of the material before granulation should be less than 200 mesh. Typical application materials: chicken manure, pig manure, cow dung, charcoal, clay, kaolin, etc. It is specially used for granulation of organic fermented fertilizers for municipal solid waste, such as organic manure, animal manure, manure, manure, composted manure, green manure, sea manure, cake manure, peat, soil and other fertilizers, three wastes, microorganisms The particles are irregular spheres. The qualified granulation rate of the granulator is over 90%, which is suitable for many different formulas. The granulator is best for direct granulation after fermentation of organic fertilizer.

Each granulator has its functions and its differences, and the disc fertilizer granulator machine also has its grading effect. The disc granulator makes the powdery material change from small to large from the bottom of the disc, and then form granules , Spilled into the outer disk. Then the diameter of its outer disc becomes larger, and the linear velocity of the particles increases rapidly. The particles are rolled while rolling to form spherical particles. Finally, the larger particles are sent to the dryer by a belt conveyor for drying.

In actual production, the disc granulator must determine the tilt angle and speed according to various raw materials. To operate. The material required for the granulation of the disc granulator is very important for its cohesiveness and plasticity. The balls with different particle sizes will leave the edge of the disc and roll down according to the different separation angles due to the different gravity In the process of continuous rolling, the ball will continuously evacuate the water in the ball out of the surface, so that the ball has a certain hardness, and then follow the edge of the plate to discharge out of the plate. If there are uneven particles, the granulator will return again to continue granulation. The granules produced are of uniform size.

The flat die extrusion granulator is mainly used for grain processing in (biological) organic fertilizer and aquaculture processing industries. The surface of the granular material processed by this machine is smooth and clean, and the hardness is moderate. The temperature rise is low during the processing, and the nutritional components in the raw material can be well maintained. Due to the low water content of particles, it is easy to store, and greatly improves the utilization rate of materials.

Process characteristics of flat die extrusion granulator:

The flat mold granulator uses a universal joint, the differential is connected with the motor, and when it works, the mixed powder materials are added into the hopper without heating and drying. After extrusion, the processed particles have smooth surface, and the internal ripening and penetration. The materials are squeezed to the bottom by the grinding wheel, and then cut off by the scraper, which has the characteristics of no return, high particle strength, and low moisture.

Working principle of flat die extrusion granulator

The flat die extrusion granulator drives the belt and pulley by the motor and transmits them to the driving shaft through the reducer, and synchronizes with the driven shaft through the split gear and works in opposite directions. The material is added from the feed hopper, extruded by the roller, demoulded and pelletized, and then conveyed to the crushing screen studio through a pair of chains. After screening and separating the finished particles (balls), the returned material is mixed with the new material, and then pelletized. With the continuous rotation of the motor and the continuous entry of materials, batch production can be realized.

The project has the advantages of low investment, short equipment flow, small land occupation, fast feeding, flexible installation, simple operation, low energy consumption, high power efficiency and high output. The low-temperature extrusion particle process below 60 ℃ is adopted: the molding rate of one-time extrusion granulation is more than 90%, no return material and no screening. As long as the water content of the raw material formula is appropriate, there is generally no need for drying equipment. (If the extruded particle finished product needs accelerated natural cooling, a cooler can be added) can be metered and packaged. The particle compressive strength is greater than 8 newtons.

The equipment is compact in structure and stable in quality, and can work continuously for 24 hours. The thread gap adjustment device is adopted for the flat die and roller, which can reduce the excessive wear of the flat die and roller. Compared with the traditional gasket method, the service life of the flat die and roller is prolonged.

Working principle: when the equipment is running, the material is squeezed to the bottom, then cut off by the scraper, and then entered into the secondary combination polishing, and rolled into a ball. The organic fertilizer flat die extrusion granulator has the advantages of high balling rate, no return material, high particle strength, uniform roundness, low balling moisture, and low drying energy consumption. Its purpose and characteristics are as follows:

1. The machine is mainly used for particle processing in organic fertilizer and aquaculture processing industries;

2. The surface of the granular material processed by this machine is smooth and clean, and the hardness is moderate. During the processing, the temperature rise is low, and the nutrients in the raw material can be well maintained.
